In terms of striker depth, Cameron Lancaster was certainly not a name any one had ever heard until he was handed his debut as a 78th minute substitute in a Premier League match against Wigan. I don't precisely remember the circumstances surrounding his inclusion in the squad, but I think players were injured and Pavlyuchenko had just been sold, so Lancaster got to play.
At the time, this signalled to many Spurs fans that the staff at Spurs believed Lancaster was much further along in his development than some of our other youth strikers, but now, more than a year later, it seems he just may have been the winner of a coin flip. I don't mean that to be harsh on Lancaster, but he has never really shown much with the Spurs youth team. Granted, most of that is due to a lengthy string on injuries, but even when he has played he hasn't been quite so convincing as some of his other counterparts.
From his bio on the Totteham Hotspur official site:
Cameron was unable to make an impression in 2008-09 due to missing eight months through injury but joined the Academy full-time in June 2009. Again, injury restricted the frontman to just seven appearance in his first full season in our Academy, 2009-10. But a number of impressive performances in our Development Squad during the 2010-11 campaign earned him his first loan move into the Football League with the Daggers in March 2011. He also scored one goal in his two appearances in the Premier Academy League in 2010-11 and was a regular in Spurs XI friendlies in 2011-12.
Unfortunately for young Cameron, he also picked up an injury last summer and that prevented him from being involved in the pre-season with new manager Andre Villas-Boas. I'm not sure if he ever fully recovered, despite what the above linked interview says. He certainly didn't feature very often in either the Next Gen Series or the U-21 Premier League during the rest of the 2012-13 season.
Lancaster will be 21 in November and he's out of contract in the summer of 2014. If Lancaster is going to show he's actually has what it takes to be a professional footballer, he has to do it this year.
